Question

If we fire a bullet in a free-falling elevator then will it form an arc or not? If not, then please tell why?

Answer 1

Yes and no

Explanation:

The vertical component of acceleration of the bullet will be the same as that of the elevator.

So in the accelerating frame of reference of the elevator, the bullet will travel only horizontally.

In the frame of reference of an observer on the ground, the path of the bullet will form an arc.
